Barometer Fortins Manufacturer,Supplier and Exporter in India

Product Code : SCL-LM-11851

Indian Lab Suppliers supplies the Barometer Fortins (Product ID: 11851) as part of its lab meters range. A Fortin barometer measures atmospheric pressure from the height of a mercury column, read against a fixed scale with a vernier.

Quick Answer

The glass tube has a nominal 6 mm bore. Dual engine-divided scales run from 675 to 820 mm Hg in 1 mm steps and from 26.5 to 32.5 inHg in 0.05 inch steps, with verniers reading to 0.05 mm and 0.002 inch. Before each reading the cistern level is set to the fixed zero pointer, so the scale always measures from the true mercury surface. The instrument is mounted on a polished wooden board for wall fixing and is supplied without mercury; fill it in a tray with gloves and good ventilation, and keep spills contained.
